Cortical activation during Pavlovian fear conditioning depends on heart rate response patterns: an MEG studyStephan Moratti
Department of Psychology, University of Konstanz, P O Box D25, D 78457 Konstanz, Germany
Brain Res Cogn Brain Res 25:459-71. 2005..The results suggest that participants expressing different HR responses also differ in their stimulus-driven neuromagnetic response pattern to an aversively conditioned stimulus...- Fear but not awareness predicts enhanced sensory processing in fear conditioningStephan Moratti
Department of Psychology, University of Konstanz, Konstanz, Germany
Psychophysiology 43:216-26. 2006..Participants in both groups reported awareness of CS-US contingencies. Awareness of stimulus contingency in fear conditioning seems not to be sufficient to elicit enhanced visual cortical processing... - Motivated attention in emotional picture processing is reflected by activity modulation in cortical attention networksStephan Moratti
Department of Psychology, University of Konstanz, Constance, Germany
Neuroimage 21:954-64. 2004..Taken together, we argue that activity in higher-order frontoparietal cortical attention networks is modulated by emotional arousal. In turn, this attention network influences activity in systems performing stimulus processing... - Additive effects of emotional content and spatial selective attention on electrocortical facilitationAndreas Keil
Department of Psychology, University of Konstanz, Germany
Cereb Cortex 15:1187-97. 2005..The data suggest that affective stimulus properties modulate the spatiotemporal process along the ventral stream, encompassing amplitude amplification and timing changes of posterior and temporal cortex... - Modulation of the C1 visual event-related component by conditioned stimuli: evidence for sensory plasticity in early affective perceptionMargarita Stolarova
University of Konstanz, Konstanz, Germany
Cereb Cortex 16:876-87. 2006..As an underlying mechanism, we discuss short-term reorganization in visual cortex, enabling sensory amplification of specific visual features that are related to motivationally relevant information... - Early modulation of visual perception by emotional arousal: evidence from steady-state visual evoked brain potentialsAndreas Keil
Department of Psychology, University of Konstanz, Konstanz, Germany
Cogn Affect Behav Neurosci 3:195-206. 2003..These findings are consistent with reentrant modulation of early visual processing by distributed networks including subcortical and neocortical structures according to a stimulus's motivational relevance... 
Tinnitus perception and distress is related to abnormal spontaneous brain activity as measured by magnetoencephalographyNathan Weisz
Department of Psychology, University of Konstanz, Germany
PLoS Med 2:e153. 2005..Surprisingly, there have been no group studies comparing abnormalities in ongoing, spontaneous neuronal activity in individuals with and without tinnitus perception...- Source distribution of neuromagnetic slow-wave activity in schizophrenic patients--effects of activationThorsten Fehr
Department of Psychology, University of Konstanz, P.O. Box D23, D-78457 Konstanz, Germany
Schizophr Res 63:63-71. 2003..Results suggest that the distribution of slow-wave activity, measured in a standardized setting, might add diagnostic information about brain abnormalities in schizophrenia... - Source distribution of neuromagnetic slow wave activity in schizophrenic and depressive patientsChristian Wienbruch
Department of Psychology, University of Konstanz, D-78457 Konstanz, Germany
Clin Neurophysiol 114:2052-60. 2003..CONCLUSIONS: Results suggest that slow wave distribution may assist in differentially diagnosing psychopathological conditions... - Neural mechanisms of evoked oscillations: stability and interaction with transient eventsStephan Moratti
Center of Magnetoencephalography Dr Perez Modrego, Facultad de Medicina, University Complutense of Madrid, Madrid, Spain
Hum Brain Mapp 28:1318-33. 2007..We conclude that ssVEPs represent strongly phase locked oscillations sharing the same generation mechanisms as early evoked potentials... - Adaptation in human visual cortex as a mechanism for rapid discrimination of aversive stimuliAndreas Keil
NIMH Center for the Study of Emotion and Attention, University of Florida, Gainesville, FL 32611, USA
Neuroimage 36:472-9. 2007..Our findings suggest that reorganization of neural connectivity on the level of the visual cortex acts to optimize early perception of specific features indicative of emotional relevance... - Brain responses to repetitions of human and animal faces, inverted faces, and objects: an MEG studyStefan R Schweinberger
Department of General Psychology, Friedrich Schiller University of Jena, Germany
Brain Res 1184:226-33. 2007..These findings suggest that repetition-sensitive brain activity approximately 250 ms reflects the transient activation of object representations, with largest responses for upright faces, in the right hemisphere... 
Hypofunction of right temporoparietal cortex during emotional arousal in depressionStephan Moratti
Center of Magnetoencephalography Dr Perez Modrego, University Complutense of Madrid, Pabellón 8, Avenida Complutense, S N, 28040 Madrid, Spain
Arch Gen Psychiatry 65:532-41. 2008..These models were derived from indirect measures such as neuropsychological tests and electroencephalography alpha band power...
